<P>PROBLEM TO BE SOLVED: To keep transparency even if sterilization treatment by heat and moisture is applied, and to have preferable gas barrier property. <P>SOLUTION: A multi-layer container in which a required sterilization treatment by heat and moisture is applied to a stored liquid agent, comprises an intermediate layer consisting of an ethylene-vinyl alcohol copolymer (EVOH), and an inside layer and an outside layer consisting of an olefin resin material. The multi-layer container is cooled with the liquid agent after the sterilization treatment, and in addition, after the cooling, the container is dried by heating. The gas barrier property and the transparency can be rapidly recovered by removing the moisture absorbed in the ethylene-vinyl alcohol copolymer during sterilization for a short time. <P>COPYRIGHT: (C)2008,JPO&INPIT |
